I’m excited to announce the launch today of Telstra One Number – new technology that connects wearable devices directly to our mobile network and extends our customer’s smartphone mobile number to the device. This new embedded SIM card technology means our customers will soon be able to make and receive phone calls, and check and send text messages, from their compatible wearable device without needing their smartphone with them.

What is eSIM technology?

eSIM literally means “embedded SIM”, and should not be confused with “soft sim” as it still requires some hardware on the device to operate. Think of it as a normal SIM that is 10 times smaller and built into the device hardware at time of manufacture. The eSIM profile is downloaded to the eSIM on the device to activate it on the network.

What are the benefits?

Up until now, customers have had to pair their smartphone with their wearable using Bluetooth to access calls, messages and notifications on their wearables. The ability to connect a wearable, like a smartwatch, directly to a mobile network and integrate an existing mobile number will make these devices even more powerful companions.

What does this mean for the future of wearables?

Telstra One Number marks an exciting new era as it paves the way for a new generation of wearables with evolved designs and voice and data integration. And because eSIMs are smaller than typical SIM cards, the technology will help designers bring connectivity and calling to a broader range of smaller wearable devices – from clothing and health monitors right through to fitness trackers and watches.

How does it work?

Once a wearable and a mobile device are successfully synced and connected to our network, both devices will share a customer’s mobile plan inclusions such as calls, text and data.

Telstra One Number will be available on a range of upcoming devices over the next 12 months. Click for more information.
